Compact 2 W polysilicon panel

This 136 by 110 millimetre polysilicon solar panel delivers 2 W at a working voltage of 12 V and a working current of 0.166 A. Weighing 0.052 kg and measuring 3 mm thick, it suits hobbyists and integrators who need a small, lightweight module for low-power outdoor or portable projects. The 17 % conversion rate provides usable output in a footprint that fits tight enclosures.

Replaces single-cell experiments

Builders who have been wiring individual solar cells by hand can substitute this encapsulated unit to gain mechanical protection and consistent electrical ratings without redesigning the voltage level. The jump is worthwhile when a project moves from bench testing to a permanent installation that must withstand weather and vibration while keeping the same 12 V operating point.

Steady output under continuous sun

Under sustained illumination the panel maintains its rated 0.166 A current without the rapid drop-off seen in bare cells that overheat in open air. The solid casing dissipates heat well enough to keep conversion efficiency stable during long daylight periods, making it reliable for lamps, sensors or trickle-charging duties that run for hours rather than minutes.

Questions about this item

What are the exact dimensions of the 136x110x3 mm panel for mounting?

The panel measures 136 mm long, 110 mm wide and 3 mm thick, so any bracket or enclosure must accommodate that footprint and low profile.

How do I connect the 12 V 0.166 A output, and what is the common wiring mistake?

Solder or crimp leads to the two rear tabs, observing polarity; the frequent error is reversing positive and negative, which prevents charging.

Will the polysilicon cells degrade and need replacement?

Polysilicon cells slowly lose output over many years; the panel itself is sealed and has no user-serviceable parts, so replacement means buying a new unit.
